       The era of ‘one-size-fits-all’ treatment approaches is becoming history for pharmaceutical 
       manufacturing with the future encountering a revolution in drug development through the 
       introduction of additive manufacturing technologies. The innovative elements of this disruptive 
       technology will affect all shareholders of the pharmaceutical chain from the industrial sector 
       to the dispensing facilities and, ultimately, the patient end-user. In this review, we provide an 
       overview  of  the  most  recent  advances  in  dosage  forms  and  devices  using  additive 
       manufacturing technologies, along with the regulatory landscape framing the development and 
       safety requirements for 3D-printed drug products before entering the pharmaceutical market. 
       Keywords: 3D printing; dosage forms; routes of administration. 
       Teaser: An outline of the latest advances in additive manufacturing of pharmaceutical dosage 
       forms and the existing regulatory framework.

                         Introduction 
                         3D printing (3DP) or additive manufacturing (AM) can be any manufacturing process used to 
                         transform a 3D digital model into a 3D physical subject by successive material deposition in a 
                         layer-by-layer  mode.  Some  of  these  techniques  [e.g.,  fused  deposition  modeling  (FDM), 
                         stereolithography (SLA), binder jetting (BJ), powder bed printing (PBP), semi-solid extrusion 
                         (SSE) and inkjet printing (IP)] have been used during the past few years for the creation of 
                         pharmaceutical formulations, with the number of published papers increasing at an exponential 
                         rate since 2014 [1] (Figure 1). 
                         Although drug 3DP technology is still in its infancy, many steps toward the enrollment and 
                         optimization of different AM technologies in drug formulation and dosage forms have been 
                         taken. For instance, new pharmaceutical-grade polymers were found to be suitable for FDM 
                         3DP operating at much lower temperatures (90°C) than conventional FDM printing, enabling 
                         printing  of  thermolabile  active  pharmaceutical  ingredients  (APIs)  [2],  and  a  variety  of 
                         biocompatible bioinks utilized in inkjet 3DP have been developed [3]. The main reason for this 
                         burst in AM is the fact that prices of 3D printers are declining steadily and rapidly. The low 
                         cost of FDM 3D printers renders them the most suitable candidate for equipping the community 
                         pharmacies  and  other  small-scale  healthcare  provision  facilities.  Moreover,  good 
                         manufacturing  practices  (GMP)-complying  FDM  printers  and  hot-melt  extruders,  for 
                         continuous and large-scale drug-loaded filament production, have recently been manufactured 
                         [4], highlighting the impending transition from proof-of-concept demonstrations toward real-
                         life applications.

                         Oral delivery 
                         Per os administration, although generally preferred for medication intake, is not ideal for the 
                         administration of APIs with a narrow therapeutic window or APIs that exhibit dose-dependent 
                                                                                                                                                                              3
